A Code in My Nodes

I have always been interested in codes and ciphers, even since I was a little kid.  I am not quite sure why.  It must lie near that perfect spot between my love of language and logic that just thrills me to no end.  My need for privacy and secrets, coupled with a unique curiosity for finding things out, just seems to blossom with coding.  I can't remember if it is my love of reading or puzzles that first got me hooked on codes, as either would have provided me with my first taste.  I remember seeing codes in the works of Poe and Doyle, as well as more age-appropriate reading, that were crucial to the plot.  I also remember simple substitution puzzles, again many not age-appropriate but still within my mental capacity, that I would try and solve.  Both would have occurred at roughly the same time, so I can't be sure which would have been first.  Regardless, I liked them, and I would try to get as much information on the subject as possible whenever I could, just like I do with any other thing I get interested in.  As with other things, my interest would wain whenever I had researched all that I could at the time.  It would still linger, in the back of my mind.  In college (actually, some of this may have started in high school), I tried to come up with a code that would be simple to implement, yet very had to decipher.  I come back to this goal every so often.  Just a few years ago, I think I finally came up with something that would fit all of my criteria.  It would be easy for someone to encode, but might be very hard for someone to crack, even with a computer.  In fact, with just a little tweaking, a computer might not be much help at all.  Of course, it would have very little use outside of puzzle making.  Once I reveal it and use even one time, its usefulness would plummet. Still, I am thinking of using it for the next puzzle I will post here.  It is taking me a few weeks to get everything together.  One you see why, you will understand why it is taking so long.  There is a lot of prep time needed for this, especially in coming up with the perfect message to be encoded.  It might be next week, but I am looking at on or two weeks after that.  It looks like this will be a short post this week, but wait until I finally can post my next puzzle.  It looks like it could be a big one.
